All I ever got was a lone Mintie inside a bag of Kool Mints. The packet is transparent but I didn't notice until I got it home... I vowed to keep it sealed because it was so cool, but one night I accidentally opened the wrong packet.
(Kool Mints are a round peppermint+nougat candy a little smaller than a marble; Minties are soft peppermint chews in a wrapper. Although they are both mint flavoured they are very different)
